Abstract
The invention discloses a compound acaricide containing diafenthiuron and pyrethrin. The compound acaricide is prepared from diafenthiuron in weight percent of 1%-30%, pyrethrin in weight percent of 1%-20% and auxiliaries. According to a large number of experimental research screening, diafenthiuron and pyrethrin are compounded in a specific mass ratio to achieve the synergistic interaction effect; under the same dosage, the compounded acaricide has an anti-mite effect superior to that of single diafenthiuron or single pyrethrin, the use concentration of the compound acaricide can be greatly reduced, the cost is low, the environment pollution is small, the drug resistance of mites can be effectively delayed, and the compound acaricide has important economic value and social value.
Description
Technical field
The present invention relates to a kind of pesticidal preparations, be specifically related to a kind of efficient miticide that diafenthiuron and pyrethrin be main active of take.
Background technology
Phytophagy evil mite, because its breeding cycle is short, individuality is little, grow the basic bionomic strategies such as fast, fertility develops immunity to drugs by force and easily, becomes one of pest being difficult to control.
Diafenthiuron chemical name is [1-tertiary butyl-3-(2,6-diisopropyl-4-Phenoxyphenyl) thiocarbamide], its commodity are called methamidophos, boccaccio, are a kind of novel Thiourea Insecticidal and acaricidal agents of brand-new chemical constitution, have tag, stomach toxicity, interior suction and fumigation action.Diafenthiuron need be under ultraviolet ray is irradiated or in polypide under the effect of mixed-functional oxidase, be decomposed into carbodiimide derivative and just there is biologically active, carbodiimides is the Fo-ATP enzyme of covalent bond mitochondrial inner membrane and Outer membrane protein and suppress mitochondrial respiratory effect optionally, hinder the performance of nerve cell mitochondrial function in pest body, affect its respiration and power conversion, thereby make insect ossified.Diafenthiuron depends primarily on the conservative of body Mitochondria to the selectivity of target organisms, therefore to mammal low toxicity, but be high poison to aquatiles such as zebra fish, river prawns, to honeybee and natural enemy insect non-selectivity.
Pyrethrin comprises what pyrethrin I, pyrethrin II, cineraria element I, cineraria element II, jasmine chrysanthemum element I and jasmine chrysanthemum element II formed.Pyrethrin directly acts on excitable membrane, disturb the ionic conduction of film, the neurilemmal sodium channel of major effect, the disappearance process that the conduction of excitation time sodium is increased delays, and causes cross-film sodium ion stream to extend, cause that Sensory nerve fibre and kinesitherapy nerve axle are repeatedly movable, of short duration nerve cell depolarising and lasting contraction of muscle, thus play the effect of paralysis insect nervous centralis, be killing insects by touching agent, good disinsection effect, action of contace poison is extremely strong, insect is difficult for developing immunity to drugs.Naturally see that light slowly decomposes except chrysanthemum element, noresidue after therefore using with the agricultural chemicals of its preparation or hygienic insecticide etc., and people and animals are had no side effect, to plant and Environmental security, be internationally recognized safest pollution-free natural insecticide.But the photostability of natural pyrethrum is poor, cause its lasting period short, while natural pyrethrum separating and extracting in pyrethrum flowers, its cost is relatively high.
But use for a long time the control of diafenthiuron and pyrethrin, the pesticide resistance of evil mite is increased the weight of day by day, cause that control of pest mite dosage is large, cost is high, weak effect, environmental pollution are serious etc., therefore necessary on the basis of prior art, the control efficiency that research and development make new advances is excellent, the low novel miticide of evil mite pesticide resistance.
Summary of the invention
